havel invented certain' new and useful Im' provements inFilm-Cartridges.; and-1 do.

' and it` has for vits lobj ect to provide simple and' in the 'kodak or McCvurdydeveloping-maeV My present invention relates-'to film-carthat type in which vthev film is wound in ay coil or "spiral with a 'covering or protecting-strip of `(ipa such as black paper, sai coveringestrip being longer than the film to cover the latter when wound with either end outermost on the coil;

efficientmeans for' adapting said film for use chines. v y l The'invention consists in certain improvements and combinations of parts, as will be hereinafter more fully described,I the novel features being pointed out in the claims 'at' the endof the specification.

In the drawings, Figure V1 is a plan view of the film-cartridge unrolled. Fig. .2 larged view of one end of the same', Fig. 3 is a sectional view on the line a; of Fig'. 1. Fig.

4 isa similar view of a modificationi Similar referencenumerals in the several figures indicate similar parts.

In carrying out my invention I provide the usual o aqu'e coveringstrip, (indicated by 1,)

' prefereJ ly of black paper, the film, (indicated order to adapt cartrid fis y 2) being'shorter than"l the covering-strip and attached thereto at Athe leading endin any suitable manner, as by the short adhesive strip 3, lapping the end of the film, In

in the developing-mac ine, it is necessary to connect the rear end ofthe film with the paper covering, so that itmay be drawn from the'spool after exposure by a tension on the paper. As in the use ofrfilrn-cartridges in rollders .or cameras .provision must be made for permitting relative movementsof the film and paper, the connection betweenthe .rear end of the film and the paper must readily accommodate itself to thsrelative movement without liability of the parts becoming separated-and at the Sametime be of such a plishthese results, .film and form near draw- 'ue iiexible material erably s es of this type for use nature that the draft paper'will drawA the 'lm from the spool and into .the developing-machine. lTo accom- I taper the rear end of the the end thereof an aperture (indicated by 4,) through which is adaptupon the end of theV I Patented fune 19';` 1

ed to. extend a tongue or loop 5, attached at its ends to the paper covering-strip, and prefer-.-

ably Ab cutting said tongue in the material thereo the free end-of said tongue being secured byl'a short sticker 6, kpreferably of waterproof material and secured by an adhesive which'isnot readily soluble in the del veloping, washing, and fixing fluids, this loop or tongue in the paper lcovering being free at the portions intermediate its endsand form-A inga loop -or-,extensible connection for the film, `whereby the lattermay be permitted to slide in either or both directions to accommodate itself to`the relativemovementsof. the

parts.

-f In Fig. 4I have shown a modification of the invention inwhich the tongue or loop e, though preferably of relatively thin' paper, is not an` integral part of-the coveringstrip, but is attached to' the latter at Opposite ends'for'- .wardlyand in. rear of the` end of the-film by adhesive material not readily soluble in the faces are secured the connection is more firm than? -whenpaper is secured to a nitrocellu lose material by an' adhesive.`

' The a erture in the end of i ightly larger than thetongueto allow both lateral and end movement of the filnnand thereby avoid binding in the camera or'roll-holder, and the outer edges of this rear end ofthe film* are made tapering,l as

above-named" fluids, andas'two paper lsurv therein is pres shown,to preventl its catching on the spools or other operating parts or. curling up in the developing apparatus when the tension is applied to the rear end of the paper covering.

This referred method of securing the end of the fi which is the following lend during the exposure, but is the endwhich is first l-Woiind upon the spool when the cartridge is formed, is sim le and cheap, as the operator spooling the mis required simply to insert e tongue throughthe aperture in the film and secure its end by the sticker, which latter covers it and adheres toith L "aper at the sides and end, and then to win t e aper and film u on the spool and securethe orwardend by 'f t ev strip-B inthe manner. .This arrangement provides also for drawin the film during the developing operation om the center, and therefore there is no necessity for reinforcing its attaching end, and there is no possibility of its becoming disconnected during development, and at the same time slight lateral and longitudinal movement may be l, permitted Without liability of the arts beand attached to one end o i covering-strip to coming' disconnected. As the en s of the loop lor tongue are secured in front and in rear of the a erture in the end ot the film, there is no liabi it of doubling the loop or unduly increasing tiie thickness ofthe roll. I claim as my inventionh Y 1. Av film-cartridge embodying a flexible photographic film p exible opaque material lon er than the lm the latter and means for loosely connecting the opposite end of the film at its central portion to the permitrelativeV longitudinal movements of the connected parts.

2; A film-cartridge embodying a flexible photographic film tapering toward-the rcenter at the rear end, a covering-strip of flexible opaque material' longer than the film and fixedly attached to one end of the latter and a loose connection located between the converging sides of the tapered end of the film and the covering-strip permitting relative movements ofthe part-s.

' 3. Affina-cartridge embodying a fiexible photographic film l endfa covering-strip of opa ue fiexible material longer than the film and vend of the latter and a loop connected at its ends to the covering stri and passing throu the aperture in the m.

4: -film-cartridge embodying a flexible photographic film having an aperture at onev end, and a vcovering-strip of fiexible opa ue material longer than the -film and .attache to photographic film having and a covering-strip of I. photographic film having having an aperture at one attached to one one end of the latter, said covering-strip hav-` ing a loop thereon connected at both its ends and passing through the aperture in the end of the film.

5.*A film-cartridge embodying a flexible a tapering end and an a erture therein, an a covering-strip of flexi le opaque material longer than the film and attached to one end of the latter, said covering-strip having a tongue thereon connected at both its ends and passing through the aperture in the end of the film.

6. Afilm-cartridge embodying a flexible photographic film 'havin y a tapering end and an a erture therein, and a covering-strip of flexi le opaque material longer than the film and attached to one end of' the latter, said covering-strip having a tongue-formed therein and assing through the a erture in the film and) means for securing t e free end of the tongue.

7A filmeartridge embodying a fiexible a covering-strip of fiexible opaque .material longer than the film andattaehed to one end ol the lat-ter, said strip having the tongue formed therein and `extending through the aperture in the film and a sticker for'securing the free end of the tongue to the strip. l

8. A film-cartridge embodying a flexible photographic film provided with an aperture 'therein and a covering-strip of opaque flexible material longer than the film and attached to one end of the latter and a connecting-loop assing loosely through the aperture in the Elm and attached to the covering-strip forwardly and in rear of the said aperture.
